The uploader states that "Most of the scratches and clicks from the recording have been removed." However, they have been removed at the expense of the good audio by a severely heavy-handed digital restoration that has introduced some very bad artifacting (very unnatural digital noise added by improper setting of the restoration controls of whatever program was used).

Just listen to the announcer's garbled voice in the first few seconds of the broadcast. Now listen to the same opening from this source with no digital processing: http://archive.org/details/OrsonWellesMrBruns

Mr. Bruns' version has the scratches and surface noise of the original transcription disc, but the announcer's voice sounds natural. Then listen to Mr. Welles' intro that follows. In the poorly-processed "scratch-free" version, his voice is muffled in and out as the program attempts to remove scratches in the recording, but also REMOVES some of the good audio of Welles' voice, and ADDS a buzzing noise not originally present. The result is a "robot-like" voice that sounds almost like the annoying Auto-Tune program heard in most pop music today. Mr. Bruns' version, on the other hand, has some surface noise, but sounds natural with no oscillating volume or buzzing. To my ears, it's a much more listenable version.

I have 10 years of digital restoration experience. The first rule is: Do No Harm, i. e., don't add noise that's not already present in the original recording. Don't try to remove all the noise in a recording, if by doing so, you destroy the original, making it sound worse. Some residual clicks, hiss, and surface noise is OK and inevitable. Restoration is always a tradeoff between noise removal and natural sound. The trick is to strike a balance so as much noise as possible is removed without damaging the ambiance, transient response, frequency response, and natural sound of the good audio. Unfortunately, the uploader tried to remove ALL the noise, and the result is unlistenable to this reviewer.

Here's another version with and without "a minor amount of EQ...and some mild cleaning" available in several file formats and bitrates that I also recommend: http://archive.org/details/WarOfTheWorlds1938RadioBroadcast256kbps The cleaned version sounds clearer, and has some clicks removed, but maintains the integrity of the original. It's a good example of the proper way to restore an old recording.
